A Random Light Observation

So the lamp in my living room has a green light bulb screwed in. Moreover, it is a lamp from Kirklands I believe, wishing it were antique (so the green light bulb seemed appropriate). While sitting on the couch in the dark, I turned on only the green light. The first thing one notices is how little it lights the room; the other side of the room was still quite dark. I then noticed that the light bursting out of the top of the lamp shade created an ovalish octagon on the otherwise black ceiling. No light came through the center of the lamp, creating a black hole within the green octagon. I noticed a slight shadow from the curtain rod on the wall. Curiously, a red cup sat on the table under the lamp shade, appearing as if it were lit from the inside. A book sat beside it: Lolita. Now I want to continue reading Lolita.
